Uploaded a new jar of the latest build (http://www.jpct.net/jpct-ae/download/alpha/jpct_ae.jar). It includes a detection of triangle strips and if it detects that an object can be rendered as a triangle strip, it will do so. Rumors are that this is faster on Android. I can't verify it, because on my phone everything is slow...

No. getPosition() is what getTranslation() or getTransformedCenter() do, setPosition() would be either translate(...) or clearTranslation();translate(...). No need to add additional methods that do the same thing.
